Vortices in 3He-A in low magnetic fields (H20 mT) have been studied by ultrasonics. A first-order phase change between two vortex types, with dissimilar sound absorption, has been found. The magnetic field at the transition is on the order of the dipolar field Hd. The observed change occurs between continuous vortex textures with different topological charges in the field (where is the magnetic anisotropy vector).
